Their sentences range from two to 17 years.
Each criminal has been sent to begin a sentence of imprisonment or youth detention during hearings held at the court in March and April 2025.
Among the crimes those on this list have been convicted of are kidnap, rape, attempted murder, blackmail, fraud and drug dealing offences.
Some of these defendants took responsibility for their crimes through guilty pleas, and consequently received a reduction in the length of their prison sentence.
Others, however, were convicted at the conclusion of trials at the same court.

Mark Evans, aged 37 (pictured left) and Robert Evans, aged 40, (pictured right) abused children in Rotherham over a two-year period starting in 2006. On March 28 at Sheffield Crown Court they were sentenced to 14 and 17 years’ imprisonment respectively for their crimes. The men, aged 18 and 21 around the time, intimidated girls and plied them with drugs and alcohol before luring them to locations where they attacked them. The brothers were arrested in August 2020 after officers from the NCA’s Operation Stovewood, examining historic sexual abuse in Rotherham, investigated allegations made by three victims.Specially-trained NCA officers spoke with the women after identifying they were potentially victims. Two of the women subsequently told specialist investigators they were raped by both brothers. | NCA
6. Osbourne Mhere and Dominic Marsden: Jailed for combined total of 176 months
A kidnap victim dumped in a bed sheet next to a busy Sheffield road spent two months in hospital because his injuries were so severe. He was slashed with a machete and a knife, and was told he would be killed as violence was meted out at a flat in Batemoor, Sheffield. The victim suffered a number of wounds to his tendons, which left him unable to use his arms or legs in the immediate aftermath of the attack, Sheffield Crown Court heard. Defendants Dominic Marsden (right) and Osbourne Mhere (left), both aged 25, were jailed for 88 months for assaulting the complainant, and their roles in the kidnapping during a hearing held on March 28, 2025. Richard Sheldon, prosecuting, said the defendants’ role extended to “bundling” the complainant into a car - assaulting him in the process - keeping him at the property, and watching on as others inflicted the injuries involving the blades. Marsden, of Lowedges, Sheffield, and Mhere both pleaded guilty to offences of kidnapping and assault occasioning actual bodily harm. Mhere also admitted possession of an offensive weapon, after police found an extendable baton - along with a stab vest - at his address on Manor Park Rise, Manor Park, Sheffield. | SYP
7. Aldo Hasani: Jailed for two years
A Sheffield teen is behind bars after he was found at a £120,000 cannabis farm during a police raid. Detectives gathered information from local communities to ascertain the location of the drug hotspot on Claremont Street, Rotherham. After breaking down the door while executing a warrant in December last year, officers found four rooms containing 117 cannabis plants, estimated to be worth up to £120,750. In a bedroom upstairs was 19-year-old Aldo Hasani, who was quickly detained. Hasani, of Cromford Street, Highfield, Sheffield, appeared before Sheffield Crown Court on January 16 where he pleaded guilty to production of a controlled Class B drug. At the same court on March 20, 2025 he was sentenced to two years to be served in a young offender institution. | SYP
8. Ramaray Treasure and James Sykes: Jailed for 25 years and eight months
Two teenagers have been jailed for a total of 25 years between them for a vicious attempted murder in Sheffield city centre. CCTV played in Sheffield Crown Court today (March 21) showed how Leon Sykes, aged19, and Ramaray Treasure, 18, chased a man on West Street and descended on him with knives. James Sykes, 19, and Ramaray Treasure, 18 (pictured right) chased their victim until he tripped in West Street, Sheffield, before "raining blows" on him with knives in hand and delivering over 30 wounds, including a punctured lung. They were jailed for a combined total of 25 years for attempted murder on March 21, 2025 The “senseless” and terrifying assault on March 9 last year saw the pair’s 24-year-old victim suffer 30 different wounds, including a punctured lung. He needed four bags worth in an emergency blood transfusion, and evidence showed the knives miraculously missed piercing his hear by a centimetre. However, the entire attack was caught live on an active CCTV camera. Just minutes after the attack, as the pair ran away to Pound’s Park and ‘high-fived’ over the beating, officers with tasers arrived and ordered them to the ground. Neither defendant has even given up why they targeted and nearly killed their victim in the first place, and the attack came after they savagely chased a different man earlier that night on Carver Street. But Judge Graham Reeds KC said in sentencing : “You both participated in a brutal and sustained attack in an attempt to murder a man you did not know over a conflict that has not been brought to light.” CCTV showed how Sykes and Treasure - who were 18 and 17 at the time - ambushed their victim near a bus stop on West Street before chasing him down until he tripped and fell. Sykes, of Victoria Street, Stocksbridge, was jailed for 13 years and eight months. Treasure, of Tansley Street, was jailed for 12 years. Both will begin their sentences in young offender institutes. | SYP
